Title: Improved magnetic layer for magnetic random access memory (mram) by moment enhancement
Inventor: JAN GUENOLE
IPC: H01L43/02
Filed: 2019-08-22
Abstract: Disclosed is a perpendicularly magnetized magnetic tunnel junction (p-MTJ), wherein a boron containing free layer (FL) is subjected to a plasma treatment with inert gas, and a natural oxidation (NOX) process is performed to form B_2O_3 before overlying layers are deposited. A metal layer such as Mg is deposited on the FL as a first step in forming an Hk enhancing layer increasing FL perpendicular magnetic anisotropy, or as a first step in forming a tunnel barrier layer on the FL. One or more annealing steps are essential in assisting B_2O_3 segregation from a free layer and increasing an FL magnetic moment. A post-oxidation plasma treatment may also be used to partially remove B_2O_3 proximate to the FL top surface before the metal layer is deposited. Both plasma treatments use low power (less than 50 Watts) to remove a maximum of 2 angstroms FL thickness.
